Claims. (Cl. 1893'4) The presentinvention relates toan insulatedlaminated metal building panel.

.Heretofore, walls such as are required for large buildings to providestructural strength, insulation and waterproof properties have usuallybeen constructed of masonry. For example, the usual masonry wall maybeapproximately twelve inches thick, that is, four inches of brick, sixinches of backup and two inches of fur-ring, lath and plaster. Thisconstruction is built by a large crew of laborers using elaboratescaffolding construction and such twelve inch thick masonry structureshave an assembly weight of approximately 78-16 pounds per square foot.Masonry construction is expensive in the first instance because ofrelatively expensive building trades fieldlabo-r and also because thistype of construction requires additional cost in foundation overconstructions having less weight per unit of wall area. Thus, reductionin cost is effected .by getting the wall units, or the principalportions thereof, pro-assembled so that the assembly time at the jobsite is kept to a minimum.

It is an object of this invention to provide a novel all metal panel forassembly on the job site, whereby all wall masonry construction iseliminated completely.

The development of the present insulated metal panel has resulted in theformation of an exterior corrugated or crested portion that permitsbreathing or the free flow of air into the panel while still preservingthe insulating and weathering characteristics of the panel. Theseattributes have not been attained heretofore.

Accordingly, another object of the invention is to provide a novellaminatedinsulated panel, whereby the above advantages are obtained.

A further object is to provide a novel positioning and mounting systemfor insulation material between metal sheets in a laminated panel.

Also generally an object is to provide an economical light weight panelfor building wall constructions having the'many foregoing attributes.

Many other objects and advantages of the present invention panel willbecome apparent from the following detailed description when read inconjunction with the accompanying drawings, wherein:

Fig. l is a front elevational view of a building wall including thepresent invention novel insulated metal building panel.

Fig. 2 is a sectional view taken along line 2-2 of Fig. 1 and through aconcrete side wall of a building structure to which the panel isanchored.

Fig. 3 is a sectional view taken along line 3-3 of Fig. 1.

In the following description like numerals throughout the severalfigures designate similar parts in the drawings.

Referring in detail to the drawings and first with particular referenceto Fig. 1, there is disclosed a complete building wall A disclosing aconcrete floor sill B with a finished floor level C, see Fig. 3. Thebuilding wall A comprises a plurality of spaced apart vertical mullions4, and each of the mullions connect with vertical elongated framemembers 5. Between frame members 5 and 2 connected suitably thereto arethe novel insulated metal panels 6 of this invention and verticallyaligned windows 7.

The panel 6 is comprisedfor the most part of sheet metal elements,namely, an interior plate 8, preferably of galvanized steel, bonderizedand painted, exterior upper and lower plates 9 and 9 each havingcorrugated or crested portions, preferably coated with porcelain enamel,side frame members 10 and 11 proportioned and shaped so as to maintainthe plates 8 and 9-9 in spaced apart relation with a sheet of insulation12 therebetween. The insulation is preferably a preformed sheet of glassfiber, see Figs. .2 and 3. In addition to the side frame members arecooperating top and bottom frames 13 and 14,,respectively, see Fig. 3.

As illustrated, the side frames 10 and 11 may be continuous and therebyserve as the side supporting frame for the windows 7 as well as theinsulated panels 6. In

any event these frame members are formed from sheet metal ,into apredetermined hollow formation having an interior side with twosurfaces, namely, a first surface 15 formed with threaded openings forthreadedbolts l6 and a second surface 17. The first surface 15 iscounter- Sunk with respect to the second surface 17, see Fig. 2, andsurface 17 of each side frame 16 and 11 is formed with a projecting bead18 formed by any suitable moulding or metal bending process. This bead18 is set back from the exterior edge of the respective side frames 1i)and 11. When each side frame is in position the bead serves as a stopfor the upper exterior plate 9, whichis secured against the stop .byangle bars I? secured to the Second surface 17 adjacent the said stopsor beads 18, as for example by bolts 29, see Fig. 2.

The lower part of the upper plate 9 is bent into a crested or corrugatedformation 21, see Fig. 2, with its free and spaced above the secondlower exterior plate 9* The lower plate 9 is likewise formed with acrested or corrugated configuration and is secured by rivets, bolts orthe like numbered 22 to a surface or step 23 formed of the bottom framemember 14. The plate 9 is directed angularly upward and inward towardthe interior plate 8 and into a holding position in contact withinsulation 12 with its crested or corrugated portion spaced from thecrested or corrugated portion 21 of upper plate 9.

The inner boundary surface of frame 1c is formed with tiers or stepsstarting with the step 23 and ending with the steps 24 and 25, whichlast two steps cooperate to mount the insulation 12 and interior plate3. For example, step 24 has anchored thereto the flange 26 of a ledge orsupport plate 27 for supporting the insulation 12], and step 25 abutsshoulder 28 of the flange 29 of plate 3. Flange 29 seats between flange26 and the riser to step 25 and plate 8 extends upwardly to be securedby bolts 30 to a flange 31 carried by the top frame member 13.

The top surface of frame 13 is made in identical step formation to frame14. The step formation of frame 13 cooperates with the window frame 32and its attached packing flange 33, while the under surface of the lowerstep of frame 13 curves under a shoulder 34 formed in the top flangededge 36 of upper plate 9 at the exterior of the panel and is sealedtherewith by a suitable mastic 35.

In mounting the interior plate 8, which is continuous, it may benecessary to adjust the same vertically for an accurate fit with respectto the upper window frame 32. To provide for this adjustment the floorsill B includes an angle brace 37 anchored by bolt 33 to the concretestructure, so that its vertical leg 39 extends upward vertically inadjusted lapped relation with respect to a downwardly extending verticalflange 40 from the rear of the step 25 of the frame 14. This lappedjoint between fianges 39 and 40 is preferably verticall slotted andprovided with securing means, such as bolts 41, which may be adjusted topermit vertical positioning of the parts.

The insulated panel by means of the crested or corrugated spaced plates9 and 9 provides a breathing space leading into the insulation materialand provides also for liberation of any water resulting fromcondensation or the like.

If desired, an elongated filter screen 44 may be positioned in the panelbetween the exterior plate 9 and the insulation 12, see Fig. 3. a

The plate 8 is flanged on each side, namely, 45 and 46 and is made tofit between the countersunk surfaces 1515 of the side frames and 11,respectively, see Fig. 2.

The bolts 16, above referred to in connection with surface 17 of frames10 and 11, serve to secure side anchor plates 45 in position on the sidewalls adjacent to surface'IS. The anchor plates are formed with aspacing shoulder 46*, so that the flanges 45 and 46 of plate '8 can fitbetween the plates beyond the shoulder and be sealed therebetween by agasket or suitable mastic material 48. The opposite end of each anchorplate 45 is angled inwardly toward the insulation 12 and formed with aretainer flange 49, which laps over the face edge of the insulation. Theflange 49 of each plate 45 may be connected together by an insulationretainer strip 50, if desired.

Each mullion 4 is comprised of angle beams 52 and 53 with legs 54, 55,56 and 57 turned outwardly at substantially right angles. The legs areanchored to cover plates 58 and 59 on the respective interior andexterior sides of the wall panel. The cover plates are formed to fitneatly in connection with the sides 10 and 11.

Thus, there is provided a novel laminated metal panel arrangementcomparable with the conventional masonry 4 to said interior plate andsaid exterior plates being in laterally spaced relation, a sheet ofinsulation disposed between .said interior plate and the innermost oneof said exterior plates, a pair of vertical step portions 011 saidbottom frame member vertically supporting said sheet of insulation, andthe innermost one of said exterior plates comprising an upwardly andinwardly directed portion whose inner edge is supportingly engaged withthe outer side wall of said sheet of insulation, said laterally spacedexterior plates providing a ventilating opening therebetween incommunication with said sheet of insulation.

2. A building construction panel according to claim 1, wherein saidinnermost one of said exterior plates includes an inwardly and upwardlydirected lower portion whose lower edge is secured to said bottom framemember, and the outermost one of said exterior plates comprising acorrugated lower portion and including a free edge portion inclinedinwardly and upwardly in parallel relation with and in spaced relationto said inwardly and upwardly directed lower portion of said innermostone of said exterior plates providing the mouth of said ventilatingopening.

3. A building construction panel according to claim 2, together with afilter screen disposed between the outermost one of said exterior platesand said sheet of insulation and in a position adjacent the upper edgeof the innermost one of said exterior plates.
